Abstract
A sheet conveying apparatus which detects an end part position of a sheet in a sheet width direction orthogonal to a conveying direction of the sheet conveyed on a sheet conveying path, comprising a plurality of sensor portions; a holding portion which holds the plurality of sensor portions; a plurality of aperture stops which is disposed between the light emitting portion and the light receiving portions and which is provided on the holding portion; and a driving portion which causes a movement of the holding portion in the sheet width direction.
Claims20
A sheet conveying apparatus which detects an end part position of a sheet in a sheet width direction orthogonal to a conveying direction of the sheet conveyed on a sheet conveying path, comprising:
- a plurality of sensor portions each of which includes a light emitting portion and a light receiving portion, and which are arranged in the sheet width direction;
- a holding portion which holds the plurality of sensor portions such that the sheet conveyed on the sheet conveying path can pass between the light emitting portions and the light receiving portions;
- a plurality of aperture members each of which has a hole portion through which light passes from the light emitting portion to the light receiving portion, and a plurality of which are provided on the holding portion corresponding with the plurality of the sensor portions;
- a driving portion which causes a movement of the holding portion in the sheet width direction;
- and
- a coupling member which couples the plurality of aperture members.
An image forming apparatus comprising:
- a sheet conveying path;
- an image forming portion which forms an image on a sheet conveyed on the sheet conveying path;
- and
- a position detecting apparatus which detects an end part position of a sheet in a sheet width direction orthogonal to a conveying direction of the sheet conveyed on the sheet conveying path,
- wherein the position detecting apparatus includes:
- a plurality of sensor portions each of which includes a light emitting portion and a light receiving portion, and which are arranged in the sheet width direction;
- a holding portion which holds the plurality of sensor portions such that the sheet conveyed on the sheet conveying path can pass between the light emitting portion and the light receiving portion;
- a plurality of aperture members each of which has a hole portion through which light passes from the light emitting portion to the light receiving portion, and a plurality of which are provided on the holding portion corresponding with the plurality of the sensor portions;
- a driving portion which causes a movement of the holding portion in the sheet width direction;
- and
- a coupling member which couples the plurality of aperture members.

- a holding portion which holds the plurality of sensor portions such that the sheet conveyed on the sheet conveying path can pass between the light emitting portion and the light receiving portion;
- a driving portion which moves the holding portion reciprocately in the sheet width direction;
- a plurality of aperture members each of which has a hole portion for regulating a direction of passing light by interrupting a part of the passing light, and each of which is disposed between the light emitting portion and the light receiving portion and is positioned according to the light emitting portion and the light receiving portion;
- and
- a coupling member which couples the plurality of aperture members.
